TIMING' MECHANISM FOR GLASS FEEDRS.

Oliginal application filed July 17, 1920, Serial No. 396,934. Divided and this application led :December` 3o, 19'25. serial No. 78,424.

My invention relates to mechanism for timing the operation of feeders for molten glass o1 the like, or of apparatus operatively 'associated with a feeder for molten glass. It isl intended more particularly as a timer for use in controlling the operation of pneumatically-operated glass feeding apparatus, but such timing apparatus may also be utilized to control the sequence of operations of various other mechanisms associated with a glass feeder or having timing requirements similar to those of glass feeders.

One object o f my invention is to provide an improved timer for opening and closing,

in proper sequence, the valves which control the operation of pneumatically actuated glass feeders or of apparatus associated therewith, and to provide means for changing at will the time when any of the valves is opened or closed.

More specifically, an object of my invention is to provide a timer of the kind indicated above, wherein changes in the time at whichthe valves are opened and closed may be made While the apparatus is in operation. Y

Glass feeders for delivering mold charges of molten glass ordinarily perform several operations which occur in timed sequence during the delivery of each mold charge to discharge and sever the glass. It is hlghly desirable that the operator be able to change the times at which these several operations take place, preferably without stopping the feeder, so that he may produce mold charges of the desired size and shape, and keep them uniform after the desired size and shape are produced. The several operations of glass feeders are frequently produced by fluid pressure, controlled by suitable valves. lhe times at which each valve is opened and closed determine the time of occurrence of the operation controlled by that valve.

In applying my presentv invention to such a duid-pressure operated glass feeder,v I

provide a timer composed of a series o1 ro.

tary valve-actuators, preferably aligned axially with one another and rotated inv unison. Two of these actuators, rotating in different planes, are preferably provided for 'of each valve.

each valve, one for openingI the valve and` theother for closing it, and

t prefer to provide the timer with means for independently adjusting the angular positions of all the valve-actuators, so as to advancev or retard at will the time at which each valvelopens and the time at Which each valve closes.

The embodimentl of m invention shown and described herein, an in my copending application for Letters Patent filed July 17 1920, Serial No. 396,934, of which the present application is a division, includes a shaft or other rotaryl axial support carrying loosely a plurality of axiallyaligned rotary cams. The driving mechanism for each of these cams includes a gear mounted on or formed integral with the cam, and a gear rigidly mounted on the supporting shaft, and these two gears are connected in driving relation by an adjustably mounted intermediate gear. The arrangement is such that all the cams are driven by the shafty .intermediate gear relative to its driving gear, and thereby changing the angular relation of the cam gear relative to the Supporting shaft.

The independently adjustable cams act through their associated valves to apply and release, in any desired sequence,'the various pressures required by the glass 'feeder or other mechanism to which the timer is applied. Also, the duration of any of these pressures Amay be adjusted by'changing the cams to vary the opening and closing time these adjustments during the continuous operation of the machine is an advantage, on account of the well-known characteristics of v glass feeding machines by which any interruption in operation causes a change vin working conditions. The operator may, in4

the present instance, observe instantly the '.efect of any such adjustment, so that the j in Fig. 2; and

to open the valve and l adjusting movement ma be continued progressively until the desired result has been obtained.

In the accompanying drawings:

Figure 1 is a front elevation, partially in section, ofl a 'timing'mechanism constructed in accordance with my invention;

Fig. 2 is a detail view, with parts in sec` tionon the line 2-2 of Fig. 1;

Fig. 3 isa plan view of partsv Fig. 4 is a front elevation, partially in section, of parts shown in Fig. 2.

Referring to the drawings, thereis shown in Fig. 1 the general arrangement of a rotary timing mechanism constructed in ac cordance with my invention, in whichl a shaft 22 forms an axial support for a plurality of actuator disks or cams 66 and 67 which are mounted loosely upon the'shaft 22, and which lactuate a setl of fluid-pressure valves 49 controlling the applicati-on and release of various pressures. The'shaft 22 is mounted in bearings 23, 2 3 provided in a suitable frame 36, and is rotated from any convenient source of power, indicated by the gear 24.

In order that thetime of occurrence and duration of any pressure may be freely adjustable, each valve.. is actuated by two separate and relatively adjustable cams, one

These cams arecall adjustablyv mounted on the shaft 22, which, -in the feeder' of my.

.original application, vactuates the glass sever- -ing mechanism,

so thatavariable timed relation is always maintained withrelation to the severing operation, and the times of As statedA above, the cams 66 and 67 are loosely by. the'shaft 22, but in orderthat the time of operation of each cam may be independently advanced orretarded there is a eared is provided Vdriving connection between 4the .sha t and each cam which is capable lof adjustment to vary the with an integral bevel gear 68 in mesh with a bevel pinion 69 freely .ro-v v tatable on a .stud 70 formed on a collar 71 also loosely Vmounted on the' shaft 22.' The collar 71 is held in adjusted position by a segmental gear.72 formed'integral there` these cams to be adjusted, and therefore, the

six shafts 74 are provided with hand wheels 76, 77, 7 8,79, 80 and 81, respectively (Fig.

:1) .A y vwhich the angular` position of the illustrated' the other to close it.

mounted on and indirectly drivenl timing of the cams. Each camseveral pinions 69 may be independentl ad justed. Each pinion 69 is driven by a evel gear 86, xed on the shaft 22. As a matter of convenience, two of bevel'gears 86, when adjacent,vare made in a single casting as shown inl Fig. 1, so as to drive adjacent cams. By this construction each cam gear 68 will be driven by a gear 86, but in the opposite direction therefrom, and the timing of each lcam may be varied by turning its hand wheel. All of the cams therefore move in unison and in th`e same direction. In this \c\onstruction, the cam' gears are placed adacent to each other between the respective fixedA gears on the shaft, and lthus the loose cam gearsv are readily maintained in definite time-relation to the apparatus to be actuated.

along the shaft in a series of pairs, and each pair 1s adapted toopen `and close a single fluid-pressure valve having movable elements conveniently located in the respectivepaths of movement of the cams.

The valve'49 is actuated by a pivoted lever '62 mounted on a suitable bracket 51 land provided with two oifset rolls 64 and 65 which are located on opposite sides of 1ts fulcrum and inoperative .relation with the actuator cams 66 and The lower extremity of the lever 62 engages a valve plunger 52. by means. of a `pin .63 and the plunger is reciprocated to -alternately open and close a port-53 in the valve casing and thereby control the flow of fluid through the communicating conduits 35, 46., 47 andv 57 in adesired manner. The specific results produced by the fluid distributed through these conduits, as applied to a glass feeding apparatus, are set forth in my original application, of which the present application is a division. 1

` From the above .construction it is obvious that the cam 66 acts through the roll 64 to rock the lever 62 into thedotted-line position shownin Fig. 2, thereby opening the' valve, and that the cam 67, acting through the roll 65, rocks thev lever 62 in the opposite direc- -ton to close the valve; The valve plunger lis yieldingly held in open or closed position by a spring-pressed detent 54 which engages one or the other of two notches v55. l. In the operation of thetimer, the shaft support is rotated at a uniform speed, thus causing the cams carried thereby to revolve in unison and since a similar individual ldrive. is providedfor each cam, all the camsl are obliged to rotate at the same speed and -in the same direction. Should it be desired to advance or retard the time at which a particular cam in the series performs its function, the angular position of the cam may be The cams may be arranged on the ,shaftk 4provi ded thereon and capable of being adjusted independently/' of every other cam in theseries, -without lo stopping the rotation of the other timer cams. This individual adjustment feature is of special importance in controlling the -seis a. vp rincipal feature of the presentv relative to the other about the said axis of 'rotation for independently changing either the time when said .valve opens or .the time when said valve closes. v

` While my invention is of special value in operating glass feeding machines and their associated mechanisms, it may also be applied to the actuation and control of various pther mechanisms.
